Hacker [Dino Segovis] wrote in to share the latest hack from his HackAWeek series, and this time around he has constructed a talk box for his bass guitar. Providing you are old enough, you probably remember when the talk box made its way into mainstream music, on the “Frampton Comes Alive” album.
The concept of a talk box is pretty simple. A small speaker is built into a sealed enclosure, which carries the sound from the musician’s guitar to his mouth via a plastic tube. The tube is placed in the musician’s mouth, near the microphone. When his mouth is moved, the sound from the guitar is modified and reflected into the microphone.
[Dino] built a similar system using his bass guitar and an amplifier hacked together from an old tape deck. He initially ran into problems with the sound not making it all the way up the tube due to the bass’ low frequency. He had an ‘Aha!’ moment and mounted the speaker on the mic rather than down on the floor, which seems to have fixed the issue.
Be sure to check out the video below to see his talk box in action.
